1.08 Ct. Green (Lime Green) Peridot from Tanzania

This peridot began its story deep within the Earth, forming millions of years ago in the upper mantle where temperatures and pressures allow olivine group minerals to crystallize, specifically the magnesium rich mineral forsterite that is the scientific basis of peridot. Magma that originated in those depths transported the nascent crystals upward, and in the case of this stone from Tanzania, basaltic volcanism provided the vehicle that brought pockets of olivine to more shallow crustal levels where cooling could preserve gem quality crystals. The lime green color of this gem is a direct consequence of trace iron substituting into the crystal lattice, and the medium intensity green you see is the result of a balanced iron content that absorbs specific wavelengths of light. Over geological time and successive cooling events, some crystals were fractured and annealed, and others remained relatively inclusion free, which accounts for the rarity of transparent material like this one. For collectors interested in complementary gemstones, a Semi Black Opal provides a striking contrast to peridot, and the listing references Semi Black Opal as an ideal pairing for set design work or for comparative study of light interaction in distinct gem species.

This specific gemstone is a transparent 1.08 carat emerald cut peridot, with dimensions 6.63 x 4.86 x 3.99 mm, exhibiting an emerald cut that emphasizes clarity and color saturation, while the excellent polish enhances light return and surface brilliance. Clarity is graded as very slightly included at eye level, which for an educated buyer indicates minor internal characteristics that do not materially detract from the visual appeal when mounted, and which are consistent with natural, untreated peridot. Color intensity is medium, offering a lively lime green that photographs and performs well under both natural and controlled lighting. There is no enhancement, confirming that the stone is in its natural state, and the documented origin of Tanzania supports geological provenance that many connoisseurs prefer. The Natural Gemstone Company offers this gem with clear grading notes and photographic documentation, and we recommend professional gemological verification for buyers seeking formal certification. This peridot is well suited to bespoke rings and pendants where the emerald cut will showcase the stone, and the combination of natural origin, transparent appearance, and precision cutting makes it a compelling choice for informed purchasers.
